Yadav K[12] writes in Indian Public Sector blog details about the 4GW power plant in Sambhar:

The project will spread across 19,000 acres at Sambhar in Rajasthan and will entail an investment of Rs 7,500 crore in the first phase. [..] The solar PV (photo-voltaic) power plant will use PV modules based on crystalline silicon technology and with an estimated life of 25 years, the solar plant can supply 6,400 million units of energy per year. It eco-friendly project will help reduce carbon dioxide emissions by over 4 million tonnes per year.

As more devices become connected to networks and the Internet — here comes the Internet of Things — more and more of them will seek to have their own power source, and currently solar power is one of the cheapest and most mobile forms of distributed energy available. [..]

If India does reach these numbers of solar-powered water pumps, it would be the largest deployment of this technology in a single country. Reducing the grid electricity usage, and the use of expensive diesel, will not only lower carbon emissions, but it could also help the power grid operators better run their networks and reduce the power costs for the farmers.
